I don't think that it's about the heaviest and most awesome arrows out there in terms of lethality, but I do think that responsible hunting requires a strong command of the current body of evidence, a complete familiarity and competence with the bow to be used, and a meticulously tuned projectile. In addition, every bowhunter needs to know their limitations and the limitations of their chosen bow/arrow combination within the context of the game they are hunting and the conditions they are hunting in.
It is a complete over-simplification to try and reduce all of the complex variables of successfully taking game with a bow and arrow to discussing arrow weight in a vacuum. Many factors exist that ultimately are a part of this equation. For example, Chad's bow weight and draw length offer him advantages that I do not have at my draw length and weight. Thus, I opt for a much heavier arrow and intentionally restrict my shot distance to under 20 yds to improve my odds of making a killing shot.
I guess that my point is that within reason,there is no absolute truth in terms of hunting weight arrows. Instead, there are pieces of the truth that many people possess based upon their own unique perspective and circumstances...and it should all be assimilated within the context of balance.
This discussion should be less about whether or not Chad's arrow weight was sufficient to kill the deer he obviously killed, and more about congratulating Chad on his achievement and focusing on what works for any one of us given our unique set of characteristics as hunting archers.
When I am hunting, my personal preference is a moderately heavy arrow with a high FOC, and a strong (usually two-blade) BH...but that's what my years of field notes have proven works best for me with my draw weight and length. I have even managed to break bone with my 47# bows with this set-up. Recently, Ed Ashby's studies have validated my findings, but with much heavier bows, arrows, and critters.
So...let's not get too judgemental about this whole issue. I like a minimum of 10 GPP of draw weight, others like 12 GPP, and Chad seems to like a bit less...maybe with a 29" draw I would to
. Let's just remember that when comparing arrows from archer to archer, we are not comparing apples to apples...so all generalizations go completely out the window.
